No NAV With HUD

I need some help from you guys. My HUD works fine but I've never had the nav instructions show up on it when there is a route going. I looked in an old forum and 3 people, each of whom had an 09 (non V) had their problems solved by a firmware update. I took my car into the dealer and they said I am up to date and that I need a new nav for $27xx. Based my past with this dealer, my confidence that they are correct in saying my firmware is fully updated is 0.

I'd like you guys to check under the diagnostics screen what your versions are. Some may know how to do this but for those who don't, the instructions are as follows:

Put the car into acc, on, or start.
Get to the map screen by pressing the globe hard key.
Press "menu" soft key.
Above the "memory points" soft key, and directly across from the title "nav menu" is a blank space. Press and hold your finger down there for about 5 seconds until a keypad appears. You are basically pressing on a hidden soft key.
When the keypad appears, type in 295660 for 2008+ cars (9448 for older.)

There are two screens we're concerned with. The "parts info" and the "soft rel."

Under parts info, what is your "navi version?"

What is your soft rel?

I'm really asking this of 2008 (and 2009?) guys because of the HUD. I'm assuming you guys get the nav stuff showing up on the HUD just fine.

Last night I unplugged all the nav plugs in the back and reconnected. No dice. What I'm hoping and expecting to hear from you is that your versions are different from mine which would tell me that in fact I do need a firmware update.

Just a tip, if you guys are on your iPhones or whatever, take a screen shot of these instructions so you can refer to them while you're pulling the info up.

Thanks in advance for taking the time out to do this crap. Appreciate it.

Way ahead of ya Carter. Called that dealer up, the guy doesn't work there anymore so I brought it up to the service guy and he was freakin clueless. Knowledge was not passed on. So I said thanks anyway.

Thanks for your help though. And yeah the HUD is really nice. Kills me that the cts never got it. Don't think the escalade did either. Vette did though.

Re: No NAV With HUD

based on what I remember about those threads I would have to bet that dealers are really only aware of the 05-07 model firmware upgrade due to the TSB.
I would wonder if the software update could be applied by the dealer if they manually went into the S/W update section on the Nav then used the TechII.
The TSB from 07 says:
Verify that the software versions are (post upgrade):
- Navigation system software version = 0FC1
- Audio system software version = 010C

What it also says (which I think may be mis-read / overlooked by most) is:
Important: If the navigation system software is the same or higher than version 0FC, the software update will not start and the navigation software update is not necessary. DO NOT insert disc 2 into the radio.

I bet that most read that as if it has 0FC then no update is possible, BUT the disc 1 update is still able to be done.

(...my dealer lost his set...ordered a spare and after 2 month or so he received only one (copied) disc and didn't get the second...gladly I could find myself a set on ebay in between... )

There was a minor typo in his python script that I fixed on my local copy so that it would function.
basically there is an offset in the loading.kwi file that makes it less readable with a hex editor, the extract module function corrects the offset from what I can tell and makes HEX editor viewing better.

There seems to be a community of people modifying their Audi Nav unit and some other units, so it was pure chance this even was able to get anything.

I grabbed the code out of the HEX output from home, this is just a re-creation of some of it on my work computer using a copy of a LOADING.KWI that I had emailed myself a while back.
Not sure what disc this loading.kwi is from (this one in particular doesn't mention the 3657 code).
The kwi file compresses quite well, the 11.4MB file was only about 4MB after being compressed, I'm thinking we should start collecting loading.kwi files from any/all Denso Nav discs for any make/model and see what we can find. Land Rover and Jaguar use Denso based navigation in some models so there might be something to be learned from them.

But it does for some reason mention "2003 KENWOOD CORPORATION" in the file, in addition to DENSO references.

Here is a copy of the kiwi.py file that has the typo corrected from his blog.
If you have access to a Linux/Unix/Mac machine you can copy the code from the section below into a file called kiwi.py and run it from terminal.

I then opened that file in a HEX editor and did some poking around, searched up the known 295660 and saw a few codes around it.
Like 660, 9448 which we already know about and then there was -> 3657, 3366 next to them as well, so I ran out to the car and tried both and the first one worked.
3657 seems to give the most diagnostic features for the 08+ model (looks like it matches what the 9448 code provides 05-07 models based on screen captures).

Re: No NAV With HUD

Well my audio version is 2.01 and my navi is 0070. So based on the navi alone, mine and yours, Luda, are off. And since your nav and HUD work together, and we both have 2008+, I truly believe I need a firmware update.

I absolutely believe that you're right in saying that since there isn't a tsb for 2008+ the dealers assume its updated. I have to venture away from my local dealer and find one that knows what they're doing. Thanks so much Luda.
